Definitions

  • the invention relates to a socket head for longitudinally divided cable fittings with a supporting body and with at least one protuberance made of heat-shrinkable material designed as a cable entry, wherein in the transition area between the protuberance and the cylindrical socket head wall, a joint joint running in the axial direction is designed for the insertion of a cable, the width of the opening area being designed in this way It is great that the cable to be inserted can be used in a snap-in manner.
  • the cable entries are often made in separate end areas, the so-called socket heads.
  • a cable sleeve is described in DE-OS-2 731 578. It consists of socket heads which are each provided with at least one cable entry designed as a protuberance and which are connected or covered with one another via a plastic shrink tube.
  • the socket heads can only be shrunk in the area of the cable entries and have a split support jacket with which the connecting edges or the webs are held together along the joint of the socket head.
  • a cable is inserted into the cable entry, especially in the case of uncut cables, via the widened parting line along a generatrix of the protuberance.
  • FR-A-2 388 432 describes a cable sleeve which is somewhat similar to the above embodiment; because here, too, parting lines are arranged along the cable entries, which allow the cables to be inserted into place. But here, too, the joints are so narrow that large cables are difficult to insert. After the cables have been inserted, the edge areas of the joints are brought together and sealed.
  • the invention was based on the object of facilitating the insertion of cables in the insertion area of the socket heads and improving the sealing along the joints in the cable entries.
  • the task is now solved on the socket heads in that the parting line of each cable entry is designed as a longitudinal, wide opening area with edge areas that cannot be merged and that a filler piece that is adapted in width is arranged in each opening area.
  • the essence of the invention can be seen in the fact that the cable to be inserted in each case can be inserted with little effort through the common longitudinal joint between the cable entry and the socket head. It is important that only a very slight widening of the parting line is necessary in order to insert the cables into the cable entries designed as protuberances. Excessive widening, as would be the case, for example, with joints with adjacent edges, is hardly possible due to the rigidity when several cable entries are made in a socket head. This problem does not apply to the socket heads according to the invention, since the parting lines in the opening area are designed to such an extent that the cables can be inserted more or less snap-in. Adapted filler pieces are then introduced into these opening areas.
  • assembly is made considerably easier if the cables to be introduced are provided with the filler pieces before they are inserted.
  • the filler is clamped onto the cable in the appropriate position using a tensioning strap or the like.
  • This also considerably simplifies additional measures relating to the interception or connection of umbrellas. This is possible in a simple manner on the filler pieces, since with the jamming on the cable the connection with the reinforcement or the shielding of the cable can be made at the same time.
  • the filler pieces also have attachment options for connecting connecting lines or connecting rails, with the aid of which a connection can also be made between the end-face socket heads. This measure serves on the one hand for electrical connection and on the other hand also for the mechanical bridging of tensile and compressive forces.
  • any torsional forces in the entry area are also advantageously absorbed, so that the sealing area is also hardly burdened by this.
  • the filler pieces are connected or fused into the opening area with the socket head wall and the wall of the cable entry designed as a protuberance with the aid of sealing adhesives, which are advantageously activated when exposed to heat. It is particularly advantageous here if the fillers themselves are already coated with the appropriate material so that it is melted down immediately when exposed to heat, which is required anyway for shrinking the cable entries. The melting process can be improved if the filler pieces are made of metal, since then particularly good heat conduction also takes place in the areas located inside and therefore difficult to access.
  • Socket heads can be used when using shrinkable as well as mechanically clampable socket cylinders.
  • a sealing system of flange-like enclosures is expediently provided on the outer circumference of the sleeve heads between the sleeve heads and this sleeve cylinder. These enclosures are provided with sealing grooves in which sealing agents are inserted. The sleeve cylinder is finally clamped over this. This also ensures that the sealing systems in the socket heads remain unaffected when the socket cylinder is reopened.
  • the insertion area of the sleeve head 1 is illustrated by the partial sectional view of the cable sleeve 11 shown in FIG. 1.
  • a cable 12 is inserted into the cable entry 2 designed as a protuberance.
  • the protuberance here is designed inwards, but the protuberance outwards is also possible, with all other conditions being the same.
  • the opening area 3 'of the parting line is covered in this figure by the overlying filler 3, which completely fills it.
  • the filler 3 has been clamped onto the cable 12 using a clamping device 9, for example a tightening strap, before the cable 12 is inserted.
  • a clamping device 9 for example a tightening strap
  • a support body 8 which is preferably made of metal, is introduced into the inside of the socket head 1 in order to give the socket head 1 the necessary support.
  • a sleeve cylinder 11 is shown, which is sealed against the sleeve head 1 via flange-like enclosures 5.
  • the sealing groove 6 can be seen, in which sealing material 10 is inserted for sealing against the sleeve cylinder 11.
  • the sealing against the respective socket head 11 is carried out by an intermediate layer of adhesive or sealant between the flange-like enclosure 5 and the outer surface of the socket head 1.
  • the flange-like enclosure 5 itself is pressed onto the socket head 1 by means of tensioning straps 7. This ensures that when the sleeve cylinder is opened, the sealing systems in the sleeve heads 1 remain unaffected.
  • the sleeve cylinder 11 of this exemplary embodiment is mounted after the assembly of the sleeve heads 1 and the flange-like enclosures 5 has been completed and is mechanically clamped by its longitudinal closures, which are not visible here, and thus pressed onto the flange-like sealing systems of the sleeve heads 1.
  • Fig. 2 the conditions in the opening areas 3 'of the parting lines at the cable entries 2 of a socket head 1 are shown. From this it can first be seen that the wall 1 'of the socket head 1 merges directly into the walls of the cable entries 2. A web-like closure area between the socket head wall 1 'and the cable entries 2 is thus not present and the support body 8 thus engages directly behind this common opening area, so that migration of the wall of the cable entries 2 near the cable 12 is not possible due to shrinking forces. When the cable entries 2 shrink, the cable 12 is thus pressed against the cylindrical part of the socket head 1, since the socket head wall 1 'is fixed by the support body 8.
  • the filler pieces 3 are now arranged, which fill the full opening area 3' of the separating joints and together with the melted-in adhesive 13 form a tight seal.
  • the outer periphery of the sleeve head 1 can its further use of suitable enclosures, such as tension belt or wire coil spans are accordingly, resulting in zusä t z-lich results in a strengthening of the sleeve head.
  • the filler pieces 3 are preferably made of metal, so that particularly good heat conduction for the sealing of the sealant 13 to the inner areas is ensured.
  • a flange-like enclosure 15 is shown on the outer circumference of the socket head 1.
  • This enclosure 15 is provided with a circumferential groove 6, in which sealing material is inserted for sealing against the sleeve cylinder.
  • the enclosure 15 is expediently transverse and provided with lugs 14 at the ends for mutual screwing, so that the individual parts can be clamped against one another by means of screws 17 through the holes 16.
  • the support body 8 used in the interior of the socket head 1 thus also forms an abutment for the externally spanned enclosure 15.
  • Fig. 4 illustrates this bracing by an end view of the socket head 1, the mutual screw connection is clear.
  • FIG. 5 illustrates the enclosure 5, which is indicated in FIG. 1.
  • the transverse enclosures 5 are tightened with the aid of tensioning straps 7.
  • the sealing groove 6 for receiving sealing means, via which the sealing to the sleeve cylinder success t .
  • the transverse division of the flange-like enclosures 5 is, however, in a win in this case angle to the circumferential direction to compensate for any circumferential tolerances. These tolerances are compensated here by corresponding transverse displacement when the enclosures 5 are clamped.
  • Sealing means 13 for sealing can also be introduced into the parting plane of the enclosures 5.
